Patent DE-4234603-A1 (DE)
Title: RDS demodulator and error-corrector - delays received signals, demodulates and corrects errors according to threshold cross-over of demodulated signals
Inventor: HENZE WERNER
IPC: H04L27/233
Filed: 1992-10-14
Abstract: The demodulator delays a received signal by a half period of a radio data signal (RDS) bit. The received and delayed signals are added vectorially to produce a rectangular signal (ZD). The phase of the rectangular signal depends on the carrier frequency signal of the received and delayed signals. The vector addition is performed digitally. After demodulation, errors can be determined through comparison between the demodulated signal and a reference signal. The errors can then be corrected. Signals are used for error correction which represent a measure of the quality of the demodulated signal. The error correction depends on whether or not cross-over of the demodulated signals is detected within a half bit period. USE/ADVANTAGE - Corrects errors before error correction of RDS with test words is carried out. Errors recognised and corrected without use of test words.

Patent DE-4302876-A1 (DE)
Inventor: SCHLUETER DIETER
IPC: H05K9/00
Filed: 1993-02-02
Abstract: In the case of a front connection, a metal sheet is used which is bent in an L-shape and produces a front limb and a base limb. A printed circuit board which is fitted with sockets on the front and with connecting blocks on the rear runs at a distance from the front limb. On one side, the printed circuit board has conductor tracks which connect connecting blocks (which are used for connection of the wires from incoming cables) to the sockets and, on the other side, it has earth tracks in which additional cable wires in the incoming cable make contact. Outer screens, which are located on the sockets, are also electrically connected to the earth tracks. In order to improve the electrical screen, it is proposed to arrange a contact element having a U-profile in the separation region between two adjacent sockets and to construct the mutually facing inner surfaces of the front limb and base limb, at least in regions, as bare, electrically conductive contact inner surfaces. The contact element is fastened by means of its U-centre web to the contact inner surface of the front limb, and its U-side webs directly touch the outer screen of the adjacent sockets. The printed circuit board is connected to the front limb via conductive spacers, one end of the spacer being seated on the contact inner surface of the front limb while the opposite end touches a contact point which is located on the front of the printed circuit board. This contact point is located on that earth track on the printed board to which the additional cable wires are also connected. <IMAGE>

Title: Railside detector registering presence of rail-borne wheel - has twin oscillator and detector coils spaced along rail for reliable presence, speed and direction indication.
Inventor: FRAUSCHER JOSEF ING
IPC: B61L1/10
Filed: 1993-05-21
Abstract: The appts. has a housing (6) mounted on the inner-side of one rail (7) contg. an oscillator (5) and covered (1) coil (2) supplied from terminals (12) which generate an AC field (3) in the path of a wheel flange (not shown).

The complete assembly is duplicated within the housing with its coil activated by a second oscillator (5) operating at a different frequency and its coil energised as before. An evaluation unit (not shown) connected to both coils registers their AC potentials which change as a wheel passes due to flux-shift. USE/ADVANTAGE - Twin detectors increase reliability and safety of system and are insensitive to transients, e.g. eddy currents, in rail. Spacing of detectors and frequency discrimination enable speed and direction to be monitored in addition to presence.

Title: Changeover valve arrangement
Inventor: GNAUERT WERNER
IPC: E03C1/02
Filed: 1993-07-14
Abstract: To ensure the reliability of a changeover valve for the selective supply of water to an outlet pipe for a bathtub or shower, a backflow preventer being arranged in the pipe to the bathtub downstream of the changeover valve, thus preventing backflow or back-suction of the water from the bathtub, it is proposed that the pipe should have arranged in it a housing which has an inlet and outlet opening and in which a backflow preventer in the form of a cylindrical sleeve with a closing member is arranged in a manner which allows it to be displaced axially to a limited extent, such that the backflow preventer is pressed against a stop formed at the downstream end of the housing by the water flowing to the bathtub, while, after the changeover operation with a vacuum arising in the pipe, the backflow preventer can move axially away from the stop to balance out the vacuum.
